>smartphones are also very popular and start around $20, computers around $50
I can't even get a used laptop for $50 in my place.
>Why do you think the same might not be true in Africa?
I can't speak for the whole of Africa. However I know two personally (Nigeria and Ghana). And a few others by acquaintances - togo, Benin...
First reason: Earning power, salaries have remained relatively static for at least 10 years but the local currencies have depreciated at least 4 times within the same period.
Second reason: Production. Computers and smartphones are produced in China and India. All components needed for these devices are available within the continent. Thus, the price would be dirt cheap there.
To put the first point in context. I'm using a 5 year old HP Envy without touch screen. I bought it for N130,000 then. The equivalent of the same laptop should cost less right? Nope. It costs N250,000+ right now.
Same thing in Ghana. 8 years ago, 1 cedi = 1usd. Now 1 cedi = 4.85 cedi. Salary for a government secondary school teacher was 800 cedi then. It's 800 cedi now.
>But they're certainly complimenting each other rather than cannibalizing.
Maybe in Asia. People who grow up using Macs find it difficult to use Windows right?
It's easy for people who grew up with PCs to use smart phones. But the reverse isn't the case. I know many people who grew up with phones but now have laptops - it's easy to spot them - they use abbreviations excessively on chat.
All they use their laptops for are movies and the occasional Microsoft word. Everything else - even gaming is done on their phones or tablets.
I hope this partly answers your question.
